Methods for producing raw materials from plant biomass
Embodiments of the present disclosure generally relate to materials and methods for producing a wide range of raw materials from plant biomass. In certain embodiments, the present disclosure provides materials and methods for efficient decortication of plant biomass using a thermally regulated process to generate reactive oxygen species in the presence of a catalyst. Embodiments of the present disclosure address the need for improved methods with which to obtain a wide range of raw materials from plant biomass without the need for industrial decortication machines and without producing harmful industrial waste.
1. A method for decortication, degumming, decontamination, whitening and softening of plant biomass, the method comprising:
submerging plant biomass material in an aqueous-based decortication solution, the aqueous-based decortication solution encompassing one or more exogenous catalysts;
heating the decortication solution containing the submerged plant biomass material to a pre-determined temperature range for a pre-determined incubation period;
introducing a reactive oxygen species (ROS) into the decortication solution adjacent to the one or more exogenous catalysts during the pre-determined incubation period at a plurality of pre-determined intervals so that the one or more catalysts interact chemically with the ROS to decorticate the plant biomass material and;
introducing an alkaline wash solution or alkaline powder into the decortication solution after the pre-determined incubation period to promote decortication, degumming, decontamination, whitening and softening of the plant biomass material.
2. The method of claim 1 , wherein the plant biomass material is from the Cannabis genus.
3. The method of claim 1 , wherein the one or more catalysts is comprised of one or more transition metals.
4. The method of claim 1 , wherein the one or more catalysts facilitates a transfer of electrons to produce a reactive oxygen species (ROS).
5. The method of claim 1 , wherein the ROS is one or more of a peroxide, hydrogen peroxide, nitric oxide, an oxygen ion, a hydroxyl ion, a hydroxyl radical, and a superoxide.
6. The method of claim 4 , wherein the one or more catalysts is an iron-based catalyst and the ROS is hydrogen peroxide, and wherein the iron-based catalyst interacts chemically with the hydrogen peroxide to produce hydroxyl radicals that decorticate the plant biomass material.
7. The method of claim 6 , wherein the iron-based catalyst is present in an amount between about 2.0 and about 6.0 grams per liter of the decortication solution.
8. The method of claim 6 , wherein the hydrogen peroxide is introduced as a 35% hydrogen peroxide solution into the decortication solution in amounts between about 0.2% and about 0.06% of the total volume of the decortication solution.
9. The method of claim 1 , the alkaline wash solution or alkaline powder includes sodium bicarbonate or sodium carbonate.
10. The method of claim 1 , wherein the pre-determined temperature range is between approximately 85-98° C.
11. The method of claim 5 , further comprising adding a reactive oxygen species (ROS) to the decortication solution after adding the alkaline wash solution or alkaline powder.
12. The method of claim 1 , wherein the biomass material is not subject to mechanical pre-treatment.
